Oracle OCI : Administer User, Groups, Compartments in the Oracle Cloud Infrastructure

In this blogpost about the Oracle Cloud Infrastructure I will describe how to administer user, groups etc. Refer to the first blogpost Getting started with the Oracle Cloud Infrastructure for explain the first steps with the OCI.

A user in the OCI can access, create and administer cloud services. The permissions for users can be consolidated in groups as policies. Policies define the allowed actions for group members and in which department.

This blog entry is the third and last part of the series „Create APEX in AWS“. Here I describe the installation and configuration of Apache Tomcat and the deployment of the ORDS application in Tomcat. Later I will explain the installation of the Webserver Nginx and configure it to access APEX via Apache Tomcat and ORDS.

Information about the installation of the APEX application in AWS can be found here. The installation and configuration of Oracle Data rest service is described  here.

Change the security settings on Exadata with the script host_access_control

About three months ago I found a script named host_access_control.

The script provides the API to managing several host access and security settings. The script is available on Compute Nodes and Storage Cells since the Exadata Software Version 11.2.3.3.0. The utility is located in /opt/oracle.cellos/host_access_control. The script is not documented in the Exadata Documentation, but in the Super Cluster documentation.

The script called with the Option „-h“ displays the help:

KVM Virtualization on top of the vmware workstation 12 guest vm‘s

Kernel-based Virtual Machine (KVM) provides a possibility to use the Oracle (or Redhat/CentOS) Linux kernel as a hypervisor.

In my example, I will configure the KVM virtualization on top of the guest vm running OEL 7.4. The guest VM is running on top of the VMWare Workstation 12.

To enable the virtualization layer select VM settings and navigate to the Processor settings. Enable the setting „Virtualize Intel VT-x/EPT or AMD-V/RVI.“

The Guest VM is now enabled for the using of the nested virtualization (such kvm). Start the Guest VM.

Install and configure KVM virtualization on the OEL 7.4 Linux
